There could be delays on Interstate 90 while crews work on patching the road. 

It will be done between the I-79 interchange and Exit 35 in Harborcreek. 

The work will happen from 8 p.m. to 6 a.m. Sunday through Friday for about three weeks starting Sept. 14, PennDOT said.

Drivers should be prepared for lane restrictions in the area, they added.
